The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope launched on 25 December 2021. It is a joint project between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). The primary scientific objectives of the JWST include studying the early universe, galaxy formation and evolution, and the formation of stars and planetary systems. The telescope is also used to study the atmospheres of exoplanets to search for signs of life. The JWST is positioned at the second Lagrange point (L2) of the Earth-Sun system, located about 1.5 million km (930,000 mi) away from Earth, and uses a 6.5-meter primary mirror to collect and focus infrared light from the most distant objects in the universe.
